Find the equation of the line with slope -4 and going through point (3,8) and then convert it to slope intercept form “y=Mx+b Please help ?

Answers

Answer 1

Answer:

y=-4x+8

Step-by-step explanation:

Since the slope is given to you, you already know part of the equation. slope is equal to mx. So y=-4x. the B in y=mx+b is y-intercept. The y intercept is where the line comes in contact with the y axis. On a coordinate plane the y intercept would be Y [ex; (x,y)]. It gives you (3,8) so the y intercept would be +8 since the point is positive and not negative.

Question 11 options:

A)

B)

96

C)

288

D)

576

Answers

Answer:

its C

Step-by-step explanation:

The area of a regular hexagon is 288 square units, which is option C.

What is a regular hexagon?

A hexagon is a six-sided polygon. And a regular hexagon means, the hexagon's sides are equal.

And no interior angle has an angle measuring more than 120°.

As per the given information, we can create 6 equal size triangles.

For that find the length of the apothem,

As per Pythagoras' theorem,

Apothem = √(10)² - (6)² = √(64) = 8.

Now, the area of the regular hexagon can be described as,

S = 6 x 1/2 x 12 x 8

S = 288 square units.

Therefore, the area of the required hexagon is 288 square units.

Answer:

x3-216#answer

The factor of the cubic polynomial x³ + 216 will be (x + 6) and (x² – 6x + 36). Then the correct option is B.

What is a factorization?

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The cubic polynomial is given below.

⇒ x³ + 216

Then the cubic polynomial is written as,

⇒ x³ + 6 × 6 × 6

⇒ x³ + 6³

We know that the formula of a³ + b³ is given as,

a³ + b³ = (a + b)(a² – ab + b²)

Compare the expression, we have a = x and b = 6. Then the expression will be

x³ + 6³ = (x + 6)(x² – 6x + 6²)

x³ + 6³ = (x + 6)(x² – 6x + 36)

The factor of the cubic polynomial x³ + 216 will be (x + 6) and (x² – 6x + 36).

Then the correct option is B.

What is an expression?

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that you work in a hospital, instructions for an instrument state that it should be cleaned in the sterilizer for two hours.

The time in minutes will be calculated as:-

Time = 2 hours

Time = 2 x 60 minutes

Time = 120 minutes
